Zoos are great for teaching kids about the different sounds that animals make. Monkeys go ooh-ooh-ooh-ooh-oh-ah, horses go nay, and lions go woof. Wait. What? A mother, taking her son around a zoo in China, thought her boy was mistaken when he pointed out the barking lion. He was right. The zoo had taken their African lion away for breeding, and subbed in an employee's large, hairy dog. The mom felt cheated.
